smanches, You can't have a pulsating magnetic field without broadcasting EM radiation it's straight up physically impossible. The only difference between these witricity experiments and getting electricity from an RF field is that the coupling is primarily magnetic. Many Am radios use loopstick antennas which rely on magnetic coupling similarly. Considering the power levels required you won't see this becoming mainstream anytime soon, there would have to be long term studies done to find out what the possible interactions are with real world objects, even the few tests that have been done are all in fully shielded rooms and people aren't allowed to be in the room during the tests. I personally think it's a great technology for power supply problems that abound, a universal charging standard that doesn't require plugs would be nice, but we know industry can't get around one standard like that, there will be a dozen or more competing standards all working similarly and intentionally incompatible with each other. The pipe dream of something like this working in large scale areas such as a room are difficult enough let alone something the size of a house.
